1. Make sure that the transmitter is powered off before turning the
receiver’ s power on. Press the receiver power key, the LCD will
glow and turn on. Then press “▲▼” to choose function and
channel, press SET key to confirm the set. Check RF and AF signal
strength when the transmitter signal becomes noisy, weak or fails.
Then press “◄” or “►” to choose a clearer channel, press SET key
to confirm.
2. Press and hold the power key for 3 seconds to turn the receiver
Off.
III. Operation of the LCD display
①RF bar indicators: 8-bar indicates the strength of radio frequency
signal.
②AF bar indicators: 8-bar indicates the strength of audio signal
③When the LCD shows FREQU, it is the current working frequency
④When the LCD shows CHANNL, it is the current working channel.
⑤6-segment shows: frequency, channel and menu.
⑥Mute sign shows that no RF signal is received.
Press and hold “SET” key to choose or confirm. Press “▲▼”
key to change current frequency or channel then press “SET” key

successfully.
Receiver LCD Display
A. Main Menu
Press “SET“ key，the picture below will present on display first
After 2-3 seconds, one of two pictures below will present: it
depends on last status before turning the system off. The CPU of
receiver remembers last status LCD displays what stored last time
when the CPU was shut off.
You can select CHANNL or FREQU when press“▲▼”key. It
shows 0-99 digits when choose CHANNL; it shows real carrier
frequency when you choose FREQU.
After your choice，Press “SET” key to confirm it，if you do not
press SET to confirm it, the receiver will return to last status to work.
The LCD will blink if no confirmation is made; this is to invite a
confirmation. If you press SET key to confirm it, the LCD will stay
firm.

B. How to adjust channel
(The LCD will display one of the above depends on last status)
Press “SET” key for 2-3 seconds, LCD will present, CH 001.
Press “◄” or “►” key to change current channel. Press “SET” key
to confirm, but the receiver will return to last channel to work after
indicator flashes 2-3 seconds if not press “SET” key.
C. How to adjust frequency
Press “SET” key for 2-3 seconds; LCD will present a number
like 798.000. Press“▲▼”key to change current working frequency,
Press “SET” key to confirm, but the receiver will return to last state
to work after indicator flash 2-3 seconds if not to press “SET” key.
D. How to adjust sensitivity of receiver
Press “SET” key for 2-3 seconds; LCD will present Squelch
like 15 dB indicates sensitivity status. Press “▲▼” key to change
current status if need. This point is a factory pre-set at: 0-40dB. 5,
10, 15, 20, 25, 30, 35, 40dB positions are to provide optimal
operation in most applications. Position at 40 dB will decrease
operating range.

7
E. System lock operation
Press “SET” key for 2-3 seconds, LCD will present as the
following diagram.
After 2-3 seconds, LCD will change to one of the following
diagrams.
It depends on the last status when LCD was turned off to see what
it will show now.
If the LCD shows LOC ON, you can do nothing on the system,
even you cannot power off the system. Only when it shows LOC
OFF, you can make changes.
If it is in LOCK ON mode, press “SET” key for 2-3 seconds,
then press “ ▲ ▼ ” key to set to LOC OFF. You can change
function at LOC OFF status. Press “SET” key to confirm it after
changing function, otherwise receiver CPU keeps last status.

How to use ACT to pair the transmitter and receiver
IR
ACT is a short for Automatic Channel Targeting. To make the
easiest and fastest channel set up between the transmitter and
receiver.
Turn both receiver and transmitter on, get the transmitter IR
window close to the receiver within 30 inches, press the SET key
on the receiver, the sign will show on the LCD, it is
transmitting the frequency info to the transmitter, as soon as the

frequency is set by the system. When the sign shows, it
means the pairing failed and you have to do it again as above
stated. Repeat the procedure; you will get the pairing done quickly.

How to get the best performance
If you are using more one set of the UHF TD-1, the following
channels are recommended to avoid interference among the
receiver modules as follows;
A 1/51 27/77 8/58 34/84 15/65
B 26/76 7/57 33/83 14/64 40/90
C 6/56 32/82 13/63 39/89 20/70
E 11/61 37/87 18/68 44/94 25/75

G 16/66 42/92 23/93 49/99 5/55
H 41/91 22/72 48/98 4/54 30/80
I 27/71 47/97 3/53 29/79 10/60
J 46/96 2/52 28/78 9/59 35/85
If you are using more than two set of the UHF TD-1 , it is better
to have the two receiver sets apart from each other, at least 20 cm
(10 inches), and the following two systems into the following
channels will be suggested to set before use. Or you can try to use
another channels for best performance no interfered such CH
4,10,28,45,57,75,78, 97 means 4 sets work together
